+For advanced users who want to make a custom image, you can install the Projector CLI in the `startup_script` of the `coder_agent` resource in a Coder template. Using the Projector CLI, you can use `projector ide autoinstall` and `projector run` to download and start a JetBrains IDE in your workspace.

+
+![IntelliJ in Coder](../images/projector-intellij.png)
+
+
+In this example, the version of JetBrains IntelliJ IDE is passed in from a Terraform input variable. You create a JetBrains icon in the workspace using a `coder_app` resource.
+
+> There is a known issue passing query string parameters when opening a JetBrains IDE from an icon in your workspace ([#2669](https://github.com/coder/coder/issues/2669)). Note the `grep` statement to remove an optional password token from the configuration so a query string parameter is not passed.

+
+> Coder OSS currently does not perform a health check([#2662](https://github.com/coder/coder/issues/2662)) that any IDE or commands in the `startup_script` have completed, so wait a minute or so before opening the JetBrains or code-server icons. As a precaution, you can open Terminal and run `htop` to see if the processes have completed.
